Microsoft MPI not read by SU2 and OpenMDAO

Question

Hi,

MPI is installed and on path in system variables, in order to run a couple of softwares, SU2 and OpenMDAO on parallel mode. All 3 are installed, but the latter 2 do not find MPI in the system, when it is in system variables within the PATH as well.
When I installed SU2, it had shown the message of MPI not found. Also, OpenMDAO does not find it when running, for which the simulations end up running in serial only..

Is there any way to make these programs read MPI?

Thank you beforehand!
